en.wikipedia.org/wiki/Friedmann_equations

The Friedmann equations start with the simplifying assumption that the universe is spatially homogeneous and isotropic, i.e. the cosmological principle; empirically, this is justified on scales larger than ~100 Mpc.The cosmological principle implies that the metric of the universe must be of the form

The Universe as an Equation. This whole idea of the relationship between 1, 2, and 0 in facilitating the universe is expressed in The Universe as an Equation: 1-1[(1-1)/x] =1 . The equation starts out with 1. Then -1 comes in to represent the idea of 2 (dueling 1’s).

en.wikipedia.org/wiki/Drake_equation

The Drake equation is a statement that stimulates intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for helping us realize how much we are a part of that universe. What the equation and the search for life has done is focus science on ...

The Friedmann Equation Alexander Friedmann of Russia is credited with developing a dynamic equation for the expanding universe in the 1920s. This was a time when Einstein, Willem de Sitter of the Netherlands, and Georges Lemaitre of Belgium were also working on equations to model the universe. Friedmann developed it as a relativistic equation in the framework of general relativity, but the ...

The's Equations Of The Universe 1749 Words | 7 Pages. Isaac Newton, famous for his equations of the forces of the universe, has been put to the test by Einstein himself. Although Newton has found the numbers and equations to describe gravity and the way nature is, he has not figured out how it really works.

Einstein’s equations which relate the scale factor a(t), energy density ρ and the pressure P for flat, open and closed Universe (as denoted by curvature constant k = 0,1,−1). Today we are going to solve Friedmann equations for the matter-dominated and radiation-dominated Universe and obtain the form of the scale factor a(t).
